Over the last hundred years, Steiner education has become established in countries around the world. One of the key concepts of this enduring pedagogy is that of the temperaments, though it has been criticised for being outmoded and unsupported by empirical research. This study will assess and evaluate potential correlations between Steiner teachers’ understanding of the temperaments and the results gained from using Buss’ and Plomin’s Emotionality, Activity and Sociability/Shyness (EAS) survey. Data will be collected by surveying parents and teachers, as well as holding teacher interviews. This data will allow potential similarities and differences to be identified highlighting the degree to which Steiner’s century-old pedagogical ideas can be supported by a standard analytical tool.
